PIPA co-sponsor Sen. Ben Cardin (D-MD) on late Friday[6] released a statement saying: “I would not vote for final passage of PIPA, as currently written, on the Senate floor.”

However, Cardin said he would remain a co-sponsor because it would give him “the opportunity to be an active participant in the process of addressing the most serious concerns raised by my constituents.”

As the letter[8] (which was cc’ed to Minority Leader Mitch McConnell (R-KY)) reads:

Since the mark-up, we have increasingly heard from a large number of constituents and other stakeholders with vocal concerns about possible unintended consequences of the proposed legislation, including breaches in cybersecurity, damaging the integrity of the Internet, costly and burdensome litigation, and dilution of First Amendment rights. Moreover, in light of potential cybersecurity implications, we believe hearing from the Administration and relevant agencies is imperative.
